What’s on TV

DANCING WITH THE STARS8 p.m. on ABC. Tom Bergeron and Erin Andrews return to host the 24th-season premiere of this ballroom dance competition that pairs celebrities with professional performers and instructors. Among this season’s contestants: Charo, Chris Kattan (“Saturday Night Live”) and the Olympic gymnast Simone Biles, as well as Nick Viall, just one week after wrapping up his starring season of “The Bachelor.”

PSYCHO (1960) 8 p.m. on TCM. Alfred Hitchcock’s shocking film features a haunting soundtrack and some of the most famous scare tactics in horror-movie history. But Bosley Crowther, who reviewed “Psycho” in The New York Times, was not impressed when the film opened. He wrote that the movie had “slow buildups to sudden shocks that are old-fashioned melodramatics, however effective and sure, until a couple of people have been gruesomely punctured and the mystery of the haunted house has been revealed.” He continued: “Then it may be a matter of question whether Mr. Hitchcock’s points of psychology, the sort highly favored by Krafft-Ebing, are as reliable as his melodramatic stunts. Frankly, we feel his explanations are a bit of leg-pulling by a man who has been known to resort to such tactics in his former films.”

BABY MAMA (2008) 8 p.m. on HBO. Tina Fey and Amy Poehler starred in this comedy about a 37-year-old single woman (Ms. Fey) who hires a silly, slap-happy surrogate (Ms. Poehler) to help her have the child she desperately wants. “The film never comes fully to term, as it were: the visual style is sitcom functional, and even the zippiest jokes fall flat because of poor timing,” Manohla Dargis wrote in The Times. “But, much like the prickly, talented Ms. Fey, it pulls you in with a provocative and, at least in current American movies, unusual mix of female intelligence, awkwardness and chilled-to-the-bone mean.” Also streaming on HBO Go and HBO Now.

HUMANS10 p.m. on AMC. The brief, seven-episode second season of this sci-fi series ends as Mattie reveals the synths’ agenda and tries to enlist Max for help. Meanwhile, Mia and Hester break into the silo while Karen makes a major decision.

WHAT WE DO IN THE SHADOWS (2015) on Amazon. Jemaine Clement, of “Flight of the Conchords,” and Taika Waititi created this mockumentary about the daily lives of four vampire housemates. “At heart a dotty look at oldsters struggling to adapt to an unwelcoming modernity, ‘Shadows’ has the bones of an anarchic sitcom,” Jeannette Catsoulis wrote in The Times. “The jokes don’t always land, but the group’s determination to befriend a bewildered techie — without eating him — is strangely touching. Once they’ve learned how to Google pictures of virgins for themselves, though, he’d better watch his back.”
